| Summary: | Gastrointestinal bleeding caused by splenic pseudoaneurysm is a rare disease. This paper reports the diagnosis and treatment of a 43 years old male case of pancreatic portal hypertension with splenic pseudoaneurysm and gastrointestinal hemorrhage caused by chronic pancreatitis. The patient had a history of pancreatitis with splenic pseudoaneurysm and was diagnosed as pancreatic portal hypertension with splenic pseudoaneurysm and colonic splenic fistula by endoscopy and imaging examination because of massive gastrointestinal hemorrhage. After splenic artery embolization, the symptoms of gastrointestinal bleeding disappeared. Two months later, abdominal CT showed that the prosplenic pseudoaneurysm had basically disappeared. This case suggests that if the patient previously suffered from pancreatitis with splenic pseudoaneurysm and presented symptoms of gastrointestinal bleeding, timely consideration should be given to the existence of arterial gastrointestinal fistula to achieve timely diagnosis and treatment to save the patient's life.
